FIELD OF INVENTION

Embodiments of the invention relate generally to the field ofcommunication systems. More particularly, embodiments of the inventionrelate to method, apparatus, and system for optimizing performance of acommunication unit by a remote server.

BACKGROUND

FIG. 1 is an exemplary prior art communication system (CS) 100 with anaccess point (AP) 101 and one or more wireless stations 102.sub.1-N. TheAP 101 exchanges user data with the one or more stations 102.sub.1-Nover wireless channels indicated by the arrows. The characteristics ofthe wireless channels and noise/interference are not constant and varyrapidly over time. For example, noise and interference levels fromnearby noise/interference sources rapidly changes that cause thecharacteristics of the wireless environment to change. To cope with suchrapid changes in the noise and interference levels, the CS 100 adaptstransmission strategies to enhance performance of CS 100. One such knownstrategy is Adaptation Algorithm. The term “Adaptation Algorithm” hereinrefers to time-varying and environment-change-dependent transmission orcontrol strategies for a CS. The adaptation algorithm is implemented inthe AP 101 that adapts the wireless channels and noise/interference forcommunication with the one or more stations 102.sub.1-N.

For instance, the transmission rate of Institute of Electrical andElectronics Engineer (IEEE) 802.11g standard based WiFi communicationsystem is rapidly adapted between 6 Mbps and 54 Mbps depending on thelink quality and the rate selection method (also known as the rateadaptation algorithm) implemented in the WiFi communication system. Suchrate adaptation algorithm within the WiFi communication system usesreal-time data that are collected by the AP 101 of the WiFicommunication system itself as an input to the adaptation algorithm 103,and a rate change in the link occurs when the real-time data meets apre-defined criteria.

A possible rate adaptation algorithm 103 is to change transmission rateof signals by the AP 101 within the WiFi communication system when themeasured RSSI (Received Signal Strength Indication) becomes too large ortoo small for the current rate in use. Another possible adaptationalgorithm 103 is to increase the transmission rate of signals by the AP101 whenever packets are successfully received by the AP 101 and/or theone or more stations 102.sub.1-N for M (e.g., 3) times and decrease ratewhenever packets are unsuccessfully received for P (e.g., 2) times.While such adaptation algorithms 103 are required for WiFi communicationsystems to function properly, the rules and thresholds used by themethods are decided by a system designer of the WiFi communicationsystem. Furthermore, a specific adaptation algorithm 103 is included inthe firmware and loaded to the WiFi communication system. Hence, theadaption algorithm 103 is static in nature.

Therefore, the actual performance of the rate adaptation algorithm 103is dependent on the assumptions made by the designer of the WiFicommunication system. These assumptions may be static assumptions thatdo not change over time. The designer's assumptions, however, may bequite different from the actual operational environments and the WiFicommunication system 100 may suffer from low performance due tonon-ideal design of the static adaptation algorithm 103.

The impact of such differences in the assumptions can be significant ina large-scale deployment where many communication devices, such as AP's,independently operate. In such a deployment, every single communicationenvironment is unique and the best adaptation method for eachenvironment can be quite dependent on its own environment.

DETAILED DESCRIPTION

Embodiments of the invention relate to method, apparatus, and system foroptimizing performance of a communication unit by a remote server. Asmentioned in the background section, the actual performance of thecommunication unit could be dependent on the assumptions made by thedesigner of the communication system. In one example, as provided in thebackground section, the actual performance of the WiFi rate adaptationalgorithm is dependent on the assumptions made by the designer of theWiFi communication system. These assumptions may be static assumptionsthat do not change over time. The designer's assumptions, however, maybe quite different from the actual operational environments and a WiFicommunication system might suffer from low performance due to non-idealdesign of the adaptation algorithm.

To overcome the above problem, the embodiments herein describe a method,system and apparatus that analyzes real-time and history of operationaldata related to a communication system and provides rules and conditionsfor the communication system to improve its performance. The rules andconditions specify the characteristics of the real-time and historicaloperational data such that the communication unit can select and use themost desired adaptation algorithm to use. In one embodiment, a remoteserver (also called an optimization center) is operable to collect andprocess large amounts of data related to the communication system anddetermine rules and conditions for the communication system that willimprove the performance of the communication system. In one embodiment,the remote server collects data periodically and provides updated rulesand conditions periodically for the communication system to adapt sothat it may improve its performance. The embodiments herein are notlimited to a communication system but can be used for any type ofcommunication system that needs to be updated over time to improve itsperformance to changing environments.

The term “performance” herein refers to a combination of factorsincluding data rate, throughput, power consumption, power, error rate,latency, jitter, etc. Improving performance of the communication systemincludes increasing data rate, throughput, reducing error rate andlatency, improving jitter, power consumption, etc for the communicatingsystem.

The technical effect of the embodiments discussed herein is theimprovement of performance of a communication system (e.g., WiFi,Digital Subscriber Line (DSL), etc) by providing the communicationsystem with rules and conditions that were previously not conceivable bythe communication system due to lack of information and processing powerneeded to generate the rules and conditions. In one embodiment, adedicated server (also referred as “remote server” or “optimizationcenter”) may be used to collect operational data related to thecommunication system, where the operational data may not be accessibleor storable by the communication system itself (e.g., data from othercommunication units or old data that cannot be stored due to memorylimitations) process the operational data and provide rules andconditions that when adapted by the communication system causes theperformance of the communication system to improve.

For example, the remote server is operable to perform a statisticalanalysis of hundreds (or even millions) of communication systems workingin a similar environment as the communication system of interest. In oneembodiment, the remote server is operable to indicate to thecommunication system of interest how it can improve its overallperformance, for example, by aggressively choosing higher transmissionrates as opposed to conservatively choosing lower transmission rates.

In one embodiment, when the WiFi communication system has the capabilityto decode and execute a pre-defined pseudo-code, the remote server canconsider many more algorithms that are known to it and send the rulesand/or conditions for the algorithm to be used by communication units.For example, the remote server develops a pseudo-code for thecommunication unit to execute so that it may improve its communicationperformance. In one embodiment, the pseudo-code is stored in the memoryof the communication unit, example memory of an Access Point. Thepseudo-code may be coded in any software coding language that isexecutable by the communication unit, example by a processor of theAccess Point. In one embodiment, as the remote server becomes aware ofnewer and better algorithms, it enforces some of the communicationsystems to use one of them by sending a proper pseudo-code to thecommunication units of the communication system.

In the following description, numerous details are discussed to providea more thorough explanation of embodiments of the present invention. Itwill be apparent, however, to one skilled in the art, that embodimentsof the present invention may be practiced without these specificdetails.

FIG. 2 is a system 220 for optimizing performance of a WiFicommunication system 200 by a remote server 204, according to oneembodiment of the invention. In one embodiment, the communication system200 is similar to the communication system of FIG. 1 , but is operableto communicate with the remote server 204 (interchangeably referred toas an optimization center). In one embodiment, the WiFi communicationsystem 200 includes an Access Point (AP) 201 which comprises a processor209, memory 210, and an adaptation algorithm 203 (which may be stored inthe memory 210). In one embodiment, the AP 201 is operable tocommunicate with one or more stations 202.sub.1-N, where N is an integerequal to or greater than 1, by WiFi signals 211.sub.1-N. The term“adaptation algorithm” is interchangeably referred to as “algorithm.”

While the embodiment of FIG. 2 illustrates a WiFi communication system200 with a single AP 201, multiple APs may be used in the WiFicommunication system 200 which are operable to communicate with theremote server 204 via the Communication Channel 208. In the embodimentsdiscussed herein the remote server 204 is not part of the communicationsystem 200. In such an embodiment, the communication channel may be oneof: the Internet, a TR-069 (Technical Report 069) compatiblecommunications protocol; a Transmission Control Protocol/InternetProtocol (TCP/IP) communications protocol; a Simple Network ManagementProtocol (SNMP) communications protocol; an out-of-band telephone lineprotocol; a Digital Subscriber Line Ethernet over Coax (DSL EOC)communications protocol; a cable control channel communicationsprotocol; a powerline control channel communications protocol; a CommandLine protocol (CLI); via a wireless device; or via a mobile device.

In one embodiment, the logic unit representing AP 201 and/or thestations 202.sub.1-N can be at least one of the following communicationunits: a base station; a wireless Local Area Network (LAN) device; aDSLAM; a gateway; a performance enhancement device; a Digital SubscriberLine (DSL) Customer Premises Equipment (CPE) modem; an in-home powerlinedevice; a Home Phoneline Network Alliance (HPNA) based device; anin-home coax distribution device; a G.hn (Global Home NetworkingStandard) compatible device; an in-home metering communication device;an in-home appliance communicatively interfaced with the LAN; a wirelessfemtocell base station; a wireless WiFi compatible base station; awireless mobile device repeater; a wireless mobile device base station;a set-top box (STB)/set-top unit (STU) customer electronics device; anInternet Protocol (IP) enabled television; an IP enabled media player;an IP enabled gaming console; an Ethernet gateway; a computing deviceconnected to the LAN; an Ethernet connected computer peripheral device;an Ethernet connected router; an Ethernet connected wireless bridge; anEthernet connected network bridge; and an Ethernet connected networkswitch.

In one embodiment, the remote server 204 is operable to communicate withthe AP 201 and/or with any or all of the stations 202.sub.1-N via thecommunication Channel 208. In one embodiment the remote server 204 is acloud server. In one embodiment, the remote server 204 comprises aprocessor 206, which may be one or more processors, a memory 207 forstoring processor executable instructions, and a database 205 to managedata related to the communication system 200.

In one embodiment, the remote server 204 performs a method foroptimizing performance of one or more communication units including theAP 201 and the stations 202.sub.1-N. In one embodiment, the remoteserver 204 is operable to collect data from the one or morecommunication units (AP 201 and/or the stations 202.sub.1-N). In oneembodiment, the remote server 204 periodically collects data from theone or more communication units. The term “periodically” herein refersto regular intervals e.g., once a day, morning and evening of every day,etc.

In one embodiment, the remote server 204 is operable to generate apolicy, for each of the one or more communication units (AP 201 and/orthe stations 202.sub.1-N) based on the collected data. In oneembodiment, the remote server 204 is operable to transmit/send thepolicy to each of the one or more communication units (AP 201 and/or thestations 202.sub.1-N). The policy generated by the remote server 204 isa result of analyzing hundreds (or even millions) of similarly situatedcommunication units. Generally, an AP does not have the processingpower, storage space, or access to large amounts of data to generate thebest policy to achieve optimal performance efficiency. Furthermore, anAP does not have access to historical data related to communication withother stations. Additionally, APs may lose data when there is poweroutage or user-initiated power cycling. The remove server 204 resolvesthe above problems and provides an optimum policy for the AP 201 to usebased on analysis of large amount of operational data of thecommunication system 200 and other similarly situated communicationsystems.

Examples of similarly situated communication systems includecommunications systems having similar communication units. For example,an AP with same power, speed, and brand, and operating with similar(i.e., within 10%) number of stations. Similarly situated communicationsystems also include communications systems in different geographicalareas.

In one embodiment, the remote server 204 transmits/sends the policy toeach of the one or more communication units (AP 201 and/or the stations202.sub.1-N) periodically. For example, the remote server 204 maytransmit/send the policy to each of the one or more communication units(AP 201 and/or the stations 202.sub.1-N) when the bandwidth usage of theAP 201 is low (e.g., the AP 201 is operating less than 50% of itscapacity to serve communication units) so that it may implement the newpolicy sent by the remote server 204.

In one embodiment, the policy comprises rules and/or conditions foroperation of the one or more communication units (AP 201 and/or thestations 202.sub.1-N). For example, the policy comprises first andsecond algorithms for adapting the AP 201 to improve its performance. Inone embodiment, the one or more communication units (AP 201 and/or thestations 202.sub.1-N) implement the policy according to time-varyingdata. In one embodiment, the time-varying data comprises locationinformation, current time, and operational data of the one or morecommunication units (AP 201 and/or the stations 202.sub.1-N). In oneembodiment, the location information is determined from a GlobalPositioning System (GPS) device or setup. The embodiments herein are notlimited to two algorithms, but any number of algorithms may be used.

In one embodiment, the communication unit (AP 201 and/or the stations202.sub.1-N) comprises a transmitter to send data to the remote server204; a receiver to receive a policy from the remote server 204; and aprocessor to execute the policy by implementing one of first and secondalgorithms based on the conditions and time-varying data. Thecommunication units generally do not have the capability in terms ofprocessing resources, access to historical operational data, access tooperational data of other similarly situated communication units, etc.Therefore, the prior art communication units cannot use such informationfor improving their performance. The transmitter discussed aboveprovides data to a central location, i.e. the remote server 204, thathas the capability in terms of processing resources, access tohistorical operational data, access to operational data of othersimilarly situated communication units, etc, so that it may use suchinformation generate rules and conditions for operating thecommunication units with enhanced performance. These rules andconditions were previously not conceivable by the communication system(e.g., communication system of FIG. 1 ) due to lack of information andprocessing power needed to generate the rules and conditions. The remoteserver 204, after computing the rules and conditions, provides the rulesand conditions to the processors of the communication units, wherein theprocessors executes their respective policies by implementing one offirst and second algorithms based on the rules and/or conditions andtime-varying data.

In one embodiment, the one or more communication units (AP 201 and/orthe stations 202.sub.1-N) are operable to receive the policy along withone of the first and second algorithms based on the conditions and/orthe time-varying data, wherein the first and second algorithms did notexist in the one or more communication units (AP 201 and/or the stations202.sub.1-N) prior to being provided by the remove server 204. In suchan embodiment, the remote server 204 installs a new algorithm 203 in theAP 201, where the new algorithm is executed by the processor 209 of theAP 201.

In one embodiment, the one or more communication units (AP 201 and/orthe stations 202.sub.1-N) are operable to receive the policy andimplement one of first and second algorithms based on the rule and/orconditions and/or the time-varying data, wherein the first and secondalgorithms previously existed in the one or more communication units (AP201 and/or the stations 202.sub.1-N). In such an embodiment, the remoteserver provides recommendations to the communication units (AP 201and/or the stations 202.sub.1-N) to use either the first or secondalgorithm so the communication system 200 may improve its performance.

The conditions may include at least one of: choice of selecting one ofthe first or second algorithms based on current SNIR (Signal to Noiseand Interference Ratio); choice of selecting one of the first or secondalgorithms based on current time; choice of selecting one of the firstor second algorithms based on operational data of the one or morecommunication units; and choice of selecting one of the first or secondalgorithms based on location information. In other embodiments, otherconditions may be used in conjunction or absence to the above listedconditions. The rules may include equations, when executed in thealgorithms, will change how the conditions are evaluated by thealgorithms.

In one embodiment, the remote server 204 generates the policy byperforming analysis on the collected data, wherein the collected datacomprises operational information and historical data about each of theone or more communication units. In one embodiment, the remote server204 applies the analysis to generate conditions for when to implementone of the first and second algorithms. In one embodiment, the remoteserver 204 generates the policy by generating a pseudo-code or code foran adaption algorithm to be executed on the one or more communicationunits (AP 201 and/or the stations 202.sub.1-N).

In one embodiment, the first algorithm comprises: monitoring receivedsignal strength indication (RSSI); and adapting a data rate according toa mapping of the RSSI from a lookup table. In one embodiment, the secondalgorithm comprises: counting a first number of consecutive successfultransmissions from the one or more communication units to othercommunication units; counting a second number of consecutive failedtransmissions from the one or more communication units to othercommunication units; adjusting a data rate when the first number exceedsa first threshold; and adjusting the transfer rate when the secondnumber exceeds a second threshold. In other embodiments, otheralgorithms may be used for first and second algorithms.

The following is an exemplary embodiment showing the process ofdetermining an optimum algorithm by the remote server 204. In oneembodiment, the remote server 204 selects one of the first or secondalgorithms for the communication units (AP 201 and/or the stations202.sub.1-N) to achieve optimal performance efficiency for thecommunication system 200. In one embodiment, first algorithm determinesdata transmission rates for the communication units based on RSSI whilethe second algorithm determines data transmission rates based on anumber of consecutive successful transmissions and on a number ofconsecutive failed transmissions. As mentioned above, in one embodiment,the communication units (AP 201 and/or the stations 202.sub.1-N) havethe first and second algorithms previously stored, but do not know whichalgorithm is more efficiency for the communication system 200. In suchan embodiment, the remote server 204 provides recommendations to thecommunication units about which algorithm to use.

In one embodiment, in the first algorithm the communication units (AP201 and/or the stations 202.sub.1-N) monitor the RSSI in real-time andadapts their transmission rates according to the instantaneous RSSIvalue using a mapping table (Table 1) as shown below. TABLE-US-00001TABLE 1 RSSI to rate mapping for first algorithm RSSI value Rate −92 dBmor below 6 Mbps −92 dBm˜−90 dBm 9 Mbps −90 dBm˜−88 dBm 12 Mbps −88dBm˜−86 dBm 18 Mbps −86 dBm˜−84 dBm 24 Mbps −84 dBm˜−82 dBm 36 Mbps −82dBm˜−80 dBm 48 Mbps −80 dBm or above 54 Mbps

Table 1 is only shown as an example and a person skilled in the artwould realize that the communication units may use different rates fordifferent RSSI values other than the ones shown above.

In one embodiment, the second algorithm for the communication units (AP201 and/or the stations 202.sub.1-N) uses a higher data rate after K(e.g., 10) consecutive successful transmissions, and uses a lower datarate after M (e.g., 2) consecutive failed transmissions. In oneembodiment, the communication units (AP 201 and/or the stations202.sub.1-N) provide to the remove server 204 operational data includingRSSI, SNR, rate used for transmitting a packet, corresponding result onsuccessful packet delivery, and other relevant data collected inreal-time. In one embodiment, communication units (AP 201 and/or thestations 202.sub.1-N) may accumulate such data within the communicationunits (AP 201 and/or the stations 202.sub.1-N) and then send theaccumulated data to the remote server 204. In one embodiment, the datatransmitted to the remote server 204 is non-real-time data because it issent after some time (e.g., end of the day).

In one embodiment, the remote server 204 stores such data in itsdatabase 205 and performs a full analysis based on all the stored dataand any other knowledge available at the remote server 204. In oneembodiment, the other knowledge includes similar statistics, as thoseprovided by the communication units (AP 201 and/or the stations202.sub.1-N) to the remote server 204, from other similar communicationunits in other similar geographical localities.

In one embodiment, the remote server 204 determines the presence ofintermittent high-power interference from other near-by WiFi systems.When other WiFis' high-power packets collide with the communicationsystem 200's packet, the packet is lost regardless of the rateselection. In one embodiment, the remote server 204 determines thatother noise or interference is never observed for the communicationsystem 200, and concludes that it is best to adapt rates for thecommunication units (AP 201 and/or the stations 202.sub.1-N) as afunction of channel strength, or RSSI, only. In such an embodiment, theremote server 204 sends a control signal to communication units (AP 201and/or the stations 202.sub.1-N) asking the communication units (AP 201and/or the stations 202.sub.1-N) to use the first algorithm all the timeinstead of the second algorithm.

In one embodiment, the remote server 204 determines that there is nohigh-power WiFi interference at all, but channel changes faster thantypical static indoor wireless channel (possibly due to people movingaround the AP 201). For example, the channel variation tends to befaster between noon and midnight. In such an embodiment, the remoteserver 204 concludes that it is best to use the second algorithm insteadof the first algorithm by the communication units (AP 201 and/or thestations 202.sub.1-N). In one embodiment, the remote server 204 maydetermine optimum values for K and M to be used by the communicationunits (AP 201 and/or the stations 202.sub.1-N) in different times of theday. For example, K=10 and M=1 between noon and midnight; and K=20 andM=2 between midnight and noon.

In one embodiment, the remote server 204 sends a control signal tocommunication units (AP 201 and/or the stations 202.sub.1-N) askingcommunication units (AP 201 and/or the stations 202.sub.1-N) to use thesecond algorithm with the optimized K and M values depending on time inthe day. In case the WiFi communication system 200 is not capable ofchanging the values of K and M as a function of time, the remote server204 can send two control signals per day, one at noon and another atmidnight.

In one embodiment, when the WiFi communication system 200 has thecapability to decode and execute a pre-defined pseudo-code, the remoteserver 204 can consider many more algorithms that are known to it andsend the rules and/or conditions for the algorithm to be used bycommunication units (AP 201 and/or the stations 202.sub.1-N). In oneembodiment, the remote server 204 develops a pseudo-code for thecommunication unit to execute so that it may improve its communicationperformance. In one embodiment, the pseudo-code is stored in the memoryof the communication unit, example memory 210 of the AP 201. Thepseudo-code may be coded in any software coding language that isexecutable by the communication unit, example by the processor 209 ofthe AP 201. In one embodiment, as the remote server 204 becomes aware ofnewer and better algorithms, it enforces some of the communicationsystems to use one of them by sending a proper pseudo-code to thecommunication units (AP 201 and/or the stations 202.sub.1-N) of thecommunication system 200.

FIG. 3 is a system 320 for optimizing performance of a DigitalSubscriber Line (DSL) communication system 300 by the remote server 204,according to one embodiment of the invention. The embodiment of FIG. 3is similar to the embodiment of FIG. 2 in concept, but applicable forDSL systems. The embodiments of the invention are not limited to DSL orWiFi communication systems, but apply to any communication system thatneeds to run/execute adaptation algorithms (also called algorithms) tocope with real-time variations in link channel, noise, interference, andother factors that affect communication performance.

In one embodiment, the DSL communication system 320 comprises a DigitalSubscriber Line Access Multiplexer (DSLAM) 301 that connects to one ormore Customer Premises Equipment (CPEs) 302.sub.1-N by means of DSLsignals 304.sub.1-N, where N is an integer equal to or greater than 1.In one embodiment, the remote server 204 performs a method foroptimizing performance of the one or more communication units includingthe DSLAM 301 and the CPEs 302.sub.1-N. In one embodiment, the remoteserver 204 is operable to collect operational data from the one or morecommunication units (DSLAM 301 and/or the CPE 302.sub.1-N). In oneembodiment, the remote server 204 periodically collects operational datafrom the one or more communication units.

In one embodiment, the operational data collected by the remote server204 includes at least one of: band preference indication; margin capmode indication; indication that margin per tone should be kept smallerthan the maximum SNR (Signal to Noise Ratio) margin; service prioritiespertaining to net data rate; service priorities pertaining to excessmargin; service priorities pertaining to excess margin per tone; servicepriorities pertaining to delay; service priorities pertaining to impulsenoise protection; indication of loading algorithms used with a first DSLsystem; indication of power allocation algorithms used with the firstDSL system; maximum attainable data rate; current data rate; margin;channel attenuation per tone; average attenuation; quiet line noise pertone; active line noise per tone; SNR per tone; transmitted PSD pertone; downstream power back-off shaped parameters (DPBOSHAPED); upstreampower back-off shaped parameters (UPBOSHAPED); echo response; bandpreference; margin cap mode; Forward Error Correction (FEC) count; codeviolation count; errored seconds; severely errored seconds; number ofretraining count; current delay; error distributions; current impulsenoise protection; or FEC and interleaving parameters. The above listedoperational data is not an exclusive list. More operational data may beused by the remote server 204 to compute rules and/or conditions for thecommunication units.

In one embodiment, the remote server 204 collects configurationparameters associated with the one or more communication units. Theconfiguration parameters include at least one of: maximum nominal powerspectral density (MAXNOMPSD); maximum nominal aggregate transmit power(MAXNOMATP); power cutback (PCB); DPBOSHAPED; UPBOSHAPED; fine gains;gi; transmit spectral scaling factors; tssi; power spectral density mask(PSDMASK); power spectral density level; maximum received power(MAXRXPWR); upstream power “back-off” parameters (UPBOKLE); margin capmode; carrier mask (CARMASK); minimum impulse noise protection (MININP);maximum delay (MAXDELAY); target margin (TARSNRM); minimum SNR margin(MINSNRM); maximum SNR margin (MAXSNRM); band preference indication(PREFBAND); target data rate; minimum data rate; maximum data rate; FECand interleaving parameters; per tone bit cap (BCAP[n]); per tone targetmargin (TARSNRM[n]); reference noise (REFNOISE). The above listedconfiguration parameters is not an exclusive list. More configurationparameters may be used by the remote server 204 to compute rules and/orconditions for the communication units.

As discussed with reference to FIG. 2 , the remote server 204 of FIG. 3is operable to generate a policy, for each of the one or morecommunication units (DSLAM 301 and/or the stations 302.sub.1-N), basedon the collected operational data, according to one embodiment. In oneembodiment, the remote server 204 is operable to transmit/send thepolicy to each of the one or more communication units (DSLAM 301 and/orthe CPE 302.sub.1-N). The policy generated by the remote server 204 is aresult of analyzing hundreds (or even millions) of similarly situatedcommunication units. The DSLAM 301 does not have the processing power,storage space, or access to large amounts of data to generate the bestpolicy to achieve optimal performance efficiency. Furthermore, DSLAM 301does not have access to historical data related to communication withother CPEs connected to other DSLAMs. Additionally, DSLAM 301 may loosedata when there is power outage or user-initiated power cycling. Theremote server 204 resolves the above problems and provides an optimumpolicy for the DSLAM 301 to use based on analysis of large amount ofoperational data of the communication system 300 and other similarlysituated communication systems. The optimum policy can be determinedbased on expert knowledge outside of the communication system where theexpert knowledge can be obtained from lab testing, simulation or anyother research methods. The policy can be adaptively modified even afterthe full deployment of the communication system, and hence does notsuffer from limited knowledge that is used at the time of manufacturingthe communication system. In the embodiments discussed herein the remoteserver 204 is not part of the communication system 300.

In one embodiment, when the DSL communication system 300 has thecapability to decode and execute a pre-defined pseudo-code, the remoteserver 204 can consider many more algorithms that are known to it andsend the rules and/or conditions for the algorithm to be used bycommunication units (DSLAM 301 and/or the CPEs 302.sub.1-N). In oneembodiment, the remote server 204 develops a pseudo-code for thecommunication unit to execute so that it may improve its communicationperformance. In one embodiment, the pseudo-code is stored in the memoryof the communication unit, example memory 310 of the DSLAM 301. Thepseudo-code may be coded in any software coding language that isexecutable by the communication unit, example by the processor 309 ofthe DSLAM 301. In one embodiment, as the remote server 204 becomes awareof newer and better algorithms, it enforces some of the communicationunits to use one or more of them by sending a proper pseudo-code to thecommunication units (DSLAM 301 and/or the CPEs 302.sub.1-N) of thecommunication system 300.

Following is an exemplary embodiment of how the remote server 204 canimprove the performance of a DSL system. In DSL systems, for example thesystem 300, downstream (DS) margin is an important line performancemetric that can be monitored by CPEs 302.sub.1-N in real-time. Ingeneral, a higher margin indicates an exponentially smaller chance oferrors for the delivery of video or data packets over DSL links304.sub.1-N. When the margin becomes very small, typically below 0 dB,the link will experience errors that can cause serious impacts on packetdelivery to the CPEs 302.sub.1-N. To prevent continuation of such anunreliable link quality over a long time, CPEs 302.sub.1-N can initiatea retraining procedure and improve the operation conditions. Theretraining procedure may take 20 to 60 seconds. In one embodiment, theabove feature of DSL systems is implemented by CPEs 302.sub.1-Nmonitoring DS margins and initializing a retraining process when themargin becomes below a pre-configured threshold value ‘T.’Conventionally, ‘T’ is set to 0 dB and controlled via the DSL line'sprofile.

The remote server 204 may collect operational and performance data ofthe DSL system 300, analyze the historical data (operational andperformance data) associated with the DSL system 300, and determine thebest estimated value of ‘T’ for each line and applies the value to eachline.

The term “line” herein refers to a communication link (wired orwireless) between the DSLAM 301 and the corresponding CPE. The value of‘T’ may be analyzed per-line basis by the remote server 204. Differentvalues of ‘T’ can be applied by the remote server 204 to different DSLlines depending on their historical and environmental characteristics.

Each CPE among the CPEs 302.sub.1-N applies an algorithm to tune itsperformance. For example, the CPE applies a rule and/or condition toadapt the value of ‘T’ in real-time as a function of the real-time data(operational and performance) that is available in the correspondingCPE. The CPEs 302.sub.1-N are operable to apply the following rules andconditions. If video traffic is observed by the CPE over the line formore than t.sub.1 (e.g., 1 minute), then the CPE updates the value of‘T’ to ‘T.sub.1’ (e.g., 2 dB). Such a rule allows the CPE to react faston pixelization problems associated with video traffic. In this example,the conditions are the choice of ‘t.sub.1’ and ‘T.sub.1’, while the ruleis the “if, then” equation. Typically each retraining process of the CPEcauses discontinuation/interruption of video and data services for ashort time (e.g., 10-45 seconds), but such an interruption can bepreferable to a persistent pixelization problem of the video traffic forseveral minutes or more. If no video traffic is observed by the CPE formore than ‘t.sub.2’ (e.g., 10 minutes) then the CPE updates the value of‘T’ to ‘T.sub.2’ (e.g., 0 dB). In this example, the conditions are thechoice of ‘t.sub.2’ and ‘T.sub.2,’ while the rule is the “if, then”equation. This rule allows the CPE to reduce the chance of initiating aretraining process that can interrupt data traffic. Data service is moreresilient to errors compared to video traffic, and the errors that canhappen for a small margin (e.g., 0-2 dB) are likely tolerable for datatraffic.

The above example of the rule and/or condition involves real-timemonitoring of the data of the DSL system 300 and real-time adaptationalgorithm within the DSL system 300. In some embodiments, the data ofthe DSL system 300 may not be entirely in real-time but the data updatemay be frequent enough (e.g., 5 minutes) to behave like real-time data.

In one embodiment, the threshold values ‘t.sub.1,’ ‘t.sub.2,’‘T.sub.1’and ‘T.sub.2’ used by the rules/conditions discussed above are notstatically kept in the DSL system 300, but optimized by the remoteserver 204. In one embodiment, the CPE continues to keep itsrule/condition, but the parameters of the rules, i.e. the thresholdvalues (conditions) ‘t.sub.1,’ ‘t.sub.2,’ ‘T.sub.1’ and ‘T.sub.2,’ areupdated in the CPEs 302.sub.1-N by the remote server 204. In such anembodiment, the remote server 204 collects and analyzes historicaloperational data and any side information (e.g., data from othersimilarly situated DSL systems) that is available at the remote server204.

Continuing with the exemplary embodiment discussed above, the remoteserver 204 will choose ‘T.sub.1’=0 dB for a DSL line if pixelization hashardly happened even for margins between 0 and 2 dB in the historicaloperational data, but will choose ‘T.sub.1’=4 dB if pixelization alwaysoccurred and continued for several minutes for margins between 0 and 4B. Such long-term adaptation of the rules by remote server 204 allowsthe DSL system 300 to perform at its optimum ability under allcircumstances. In one embodiment, the switching of modes discussed abovehappens in real-time or very frequently, but the update of thresholdvalues or rules to be used by the CPEs 302.sub.1-N happens at a muchlower frequency. In one embodiment, the remote server transmits theupdated policy (with new threshold values) to the DSL system 300 a onceper day.

While the embodiments of FIG. 3 are discussed in terms of margin andvideo traffic in the DSL system 300, the embodiments can be applied toany DSL or other communication system adaptation algorithm that reactsin real-time to other data parameters without changing the essence ofthe embodiments of the invention.

FIG. 6 is a processor-based system 600 having machine-readable storagemedium with computer executable instructions 604 for optimizingperformance of the communication system by a remote server, according toone embodiment of the invention. Machine-readable storage medium is oneof 207, 210, or 310 (collectively referred to as “207/201/310”). Thecomputer/machine-readable/executable instructions are executed by aprocessor (e.g., processor 206 of the remote server, or processors 209and 309 of the AP 201 or DSLAM 301 respectively). Elements ofembodiments are also provided as a machine-readable medium for storingthe computer-executable instructions (e.g., instructions to implementthe flowcharts of FIGS. 4-5 and other processes discussed in thedescription).

In one embodiment, the processor-based system 600 further comprises adatabase 601 to store data used by the instructions 604. In oneembodiment, the processor-based system includes a network interface 602to communicate with other devices. In one embodiment, the components ofthe processor-based system 600 communicate with one another via anetwork bus 603.

The various appearances of “an embodiment,”“one embodiment,” or “some embodiments” are not necessarily allreferring to the same embodiments. If the specification states acomponent, feature, structure, or characteristic “may,” “might,” or“could” be included, that particular component, feature, structure, orcharacteristic is not required to be included. If the specification orclaim refers to “a” or “an” element, that does not mean there is onlyone of the elements. If the specification or claims refer to “anadditional” element, that does not preclude there being more than one ofthe additional element.

While the invention has been described in conjunction with specificembodiments thereof, many alternatives, modifications and variations ofsuch embodiments will be apparent to those of ordinary skill in the artin light of the foregoing description.

For example, the embodiments discussed above can apply to acommunication system comprising a performance enhancement device. Aperformance enhancement device may comprise a signal conditioningdevice, a diagnostic and remedy guidance device, or a noise cancellationdevice. A noise cancellation device, among other things, acts to cancelnoise and interference present on the DSL line, either autonomously orin conjunction with commands from the remote server. In one embodiment,the performance enhancement device is communicatively coupled to theremote server 204 via the Communication Channel 208. In such anembodiment, impulse noise cancellation feature of the performanceenhancement device may be turned on and off based on the real-timeobservation of noise, and the actual algorithm for deciding on-off canbe distributed where long-term thresholds/rules and conditions arecalculated by the remote server 204 and transmitted to the performanceenhancement device. In one embodiment, the remote server 204 forces theactual transition in the performance enhancement device as a function ofreal-time observation of the noise data.

Another alternative embodiment related to a WiFi system is described asfollows. In a typical WiFi communication system, Carrier Sense MultipleAccess (CSMA) protocol is used for multiple access. Due to the nature ofwireless channel, some of the stations (clients) might not be able tohear each other while both can reach the AP with strong power. Thisphenomenon is known as Hidden Node problem. One way to resolve thisproblem is to schedule the data transmission using Request to Send (RTS)and Clear to Send (CTS) mechanisms. Such a use of RTS/CTS incursoverhead in channel usage, but prevents disastrous packet collisions bythe two stations.

In one embodiment, the remote server 204 collects operational andperformance data of the WiFi AP 201 (and other APs) and/or stations202.sub.1-N. In one embodiment, the remote server 204 analyzes thehistorical data and determines the best value for each AP (on or off)and applies the value to each AP. In one embodiment, the value isanalyzed per-AP by the remote server 204, and therefore different valuescan be applied to different APs depending on their data characteristics.

In one embodiment, each AP is operable to apply a rule with conditionsto adapt RTS/CTS on/off in real-time as a function of real-time dataavailable to the local AP. In one embodiment, the rule generated byremote server and made available in the AP is that if a large packeterror rate is detected for more than t.sub.1 (e.g., 1 minute), the APturns on RTS/CTS. In one embodiment, the rule generated by remote serverand made available in the AP is that if a large packet error rate is notdetected for more than t.sub.2 (e.g., 10 minutes), then the AP turns offRTS/CTS.

In the above embodiment, two or more operation modes are described incontext of a local communication device (e.g., AP) selecting theoperation mode to use in real-time. In one embodiment, the selection ofthe operation mode is a function of the real-time data that is locallyavailable. In other embodiments, the data might not be in real-time butthe data update may be frequent enough for this idea to consider thedata as real-time.

In one embodiment, the rules and/or conditions e.g., the thresholdvalues ‘t.sub.1’, and ‘t.sub.2,’ and equations applying them, are notstatically kept as in AP, but optimized by the remote server 204. In oneembodiment, the threshold values ‘t.sub.1’, and ‘t.sub.2,’ and/or theequations are updated by the remote server 204 using historical data andany side information that is available at the remote server side. In theabove alternative embodiment, RTS/CTS was involved, however, the essenceof the embodiments can be applied to any WiFi adaptation algorithm thatreacts in real-time to other data parameters. WiFi adaptation algorithmsinclude control of fragmentation, channels, association, etc.
